Most people have at least seen those cheap component testers you can buy on the Chinese websites for $10 or so. If you haven’t seen them before, they usually have some kind of multi pin socket.

电容值决定电压纹波，因此电容器的额定值必须能够承受均方根 (RMS) 电流纹波。 RMS 电流计算假设仅存在一个输入电容器，并且没有等效串联电阻 (ESR) 或等效串联电感 (ESL)。有限的输出电感会导致输入侧的电流纹波，如图2所示。 图 2 TI 的 Power Stage Designer 软件 ...

输出电压纹波 对输出电压纹波的简单理解是，假设总输出电流纹波通过输出电容组的有效等效串联电阻(ESR)，导致成正比的压降。该压降表现为转换器输出端的稳态电压波形。更详细的分析需要考虑每个输出电容中的实际电容以及电容寄生和布局寄生。然而 ...
